40x8x15 Sapphire IPL Crystal
IPL sapphire crystal, also called IPL light guite, IPL lightguide, IPL crystal are the key optical element for IPL (Intense pulsed light) machine,
which filter the UV wave and reserve the useful wave from 400-1200nm for cosmetic laser, such as hair removal, vascular and acne treatment.
It is the best choose used for beauty laser IPL machines.
